San Francisco police received a report of a suspicious package inside of a building in the 400 block of Montgomery Street shortly before 8 a.m., Officer Gordon Shyy said.
Wells Fargo spokeswoman Holly Rockwood confirmed that the object was found inside the company's headquarters at 420 Montgomery St.
Montgomery Street is closed to traffic between Sacramento and California streets, and there is no estimate yet for when it will reopen, Shyy said.
